MoistTech utilizes near-infrared (NIR) sensors technology that enables noncontact measurement of the moisture content of polyvinyl butyral (PVB) pellets or film. Said to be insensitive to material variations such as particle size, material height and color, the sensors provide a continuous, reliable reading with zero drift and no maintenance. There is a one-time calibration with a non-drift optical design which enables operational personnel to make immediate line adjustments based on real-time measurements.

MoistTech can measure moisture levels in PVB to ppm levels, enabling manufacturers to accurately control and monitor the process. Glass manufacturers see excessive moisture in PVB when laminating the product. The IR3000 can measure the raw film prior to use in production and more interestingly after the glass has been completed. By physically passing the laminated product through the NIR sensor, moisture can instantly and accurately be determined.

The online sensors can be installed into any hopper, silo, material line, belt or screw conveyor, and the moisture results are displayed onto an external display or PC.

Installing a moisture measurement and control system prevents bad product due to undesirable moisture levels. Fine-tuning the setup and process of the manufacturing line enables instant improvements both in the product and in the efficiency in which it is produced.
